Replacing a 16,500-hp Adjustable Frequency Drive System: Best Practices to Maximize Uptime and Minimize Execution Risks

The application and installation of high-power adjustable frequency drives (AFDs) in the oil and gas industry require a significant allocation of resources and a large toolbox in the evaluation and deployment of tailing pumps as capital equipment. This article describes the successful installation of a 16,500-hp, medium-voltage AFD replacing an existing tailing pump AFD in an effort to increase process availability. This case study was written to provide a road map of key performance indicators, AFD design characteristics, life-cycle phases, and target measures used to support the goals and objectives of efforts in engineering, operations, and maintenance planning.
